Tags: This study systematically reviews the non-traditional pharmacological effects of diclofenac, a well-known nonsteroidal anti-inflammatory drug, to explore its potential for drug repositioning beyond its established analgesic and anti-inflammatory applications. A comprehensive literature search was conducted using the PubMed, Scopus and Web of Science databases, covering studies from 1981 to 2025. It was revealed that over 94% of records in Scopus and Web of Science are duplicated in PubMed, so the latter was used for the search in our study. After duplicate removal and independent screening, 89 from 1123 retrieved studies were selected for the search. The analysis revealed a broad spectrum of diclofenac’s non-traditional pharmacological activities, including neuroprotective, antiamyloid, anticancer, antiviral, immunomodulatory, antibacterial, antifungal, anticonvulsant, radioprotective, and antioxidant properties, primarily identified through preclinical In vitro and In vivo studies. These effects are mediated through diverse molecular pathways beyond cyclooxygenase inhibition, such as modulation of neurotransmitter release, apoptosis, and cellular proliferation. Diclofenac showed potential for repositioning in oncology, neurodegenerative disorders, infectious diseases, and immune-mediated conditions. Its hepatotoxicity and cardiovascular risks necessitate strategies like advanced drug formulations, dose optimization, and personalized medicine to enhance safety. Large-scale randomized clinical trials are essential to validate these findings and ensure safe therapeutic expansion., diclofenac; non-traditional pharmacological properties; neuroprotective; anticancer; antimicrobial; anticonvulsant; radioprotective; antioxidant; immunomodulatory; antiviral
